To completely disable "2-finger Tap as Right Click", try setting TapButton2 = 0. To temporarily change the setting, you can use the synclient program. To make it permanent, change the value in the Synaptics section of your xorg.conf file, and restart X. -Dan > TapButton3 = 2 > ClickFinger1 = 1 > ClickFinger2 = 1 > ClickFinger3 = 1 > CircularScrolling = 0 > CircScrollDelta = 0.1 > CircScrollTrigger = 0 > CircularPad = 0 > PalmDetect = 0 > PalmMinWidth = 10 > PalmMinZ = 199 > CoastingSpeed = 20 > CoastingFriction = 50 > PressureMotionMinZ = 29 > PressureMotionMaxZ = 159 > PressureMotionMinFactor = 1 > PressureMotionMaxFactor = 1 > GrabEventDevice = 1 > TapAndDragGesture = 1 > AreaLeftEdge = 0 > AreaRightEdge = 0 > AreaTopEdge = 0 > AreaBottomEdge = 0 > > A few of the fields are suggestive, but I don't really understand much > of it.
